What Polution Control Systems / PCS Co., Ltd, - 代表者 does

PCS Co., Ltd. (株式会社ピーシーエス, headquartered in Sapporo, Hokkaido) is a privately held Japanese environmental engineering firm founded in 1979 as Akushuu Shori Center Co., Ltd. and renamed in 1991. Operating with approximately six employees and a network of roughly 20 subcontractors, PCS provides design, construction, installation, and ongoing technical management of wastewater treatment systems, exhaust gas / deodorization equipment, industrial waste processing facilities, and radioactive contamination remediation systems for enterprise and government clients across Japan.

The company's core technology portfolio rests on a dense patent stack (13+ granted Japanese patents with several PCT international filings) covering four proprietary platforms: pressurized flotation treatment using ultra-fine bubble technology (Patent 6120427); subcritical water treatment for converting industrial waste into reusable outputs such as liquid fertilizer, compost, and coal substitute fuel (Patents 6327993, 6377087); radioactive contamination countermeasures validated through demonstration tests in Minamisoma and Koriyama, Fukushima (multiple patents including 5438740, 6044003, 6198145, 6198165, 6284156); and biological / activated sludge, membrane, neutralization, sludge dewatering, deodorization, and CNT ultrasound dispersion systems as supporting equipment. The integrated SLIX decontamination system combines multiple PCS technologies into modular configurations for varied radioactive contamination scenarios.

Commercially, PCS operates a direct enterprise field sales model, taking comprehensive design responsibility on large projects and supervising subcontracted installation work, with domestic sales concentrated in Japan across Hokkaido (primary base) and projects executed in Fukushima, Ibaraki, Tokyo, Shizuoka, Nagano, Gifu, Miyazaki, Aomori, and Kagoshima. Revenue is generated through one-time equipment installation and construction contracts, recurring technical management and maintenance services, environmental consulting, and managed industrial waste processing under multiple specialized Japanese regulatory permits (industrial waste collection/transport, disposal, and specially managed disposal licenses). Channel partners include Tsurumi Manufacturing and Daimei Chemical (distribution agreements since 1991), with strategic co-development partnerships with NSP Co., Ltd. and Nanosummit for Fukushima decontamination work and Ruclue Co., Ltd. for the Farm Beacon Manager monitoring software. Customer concentration is dispersed across healthcare (national hospitals), government (Hokkaido Development Bureau, Sapporo City, national hospital organizations), food processing and aquaculture (Kaneshime Shokuhin, others), livestock and agriculture (Suzuki Chikusan, Rinkai dairy farms), manufacturing (Seiko Polymer, Pentel, Heikin Industries), and environmental services (Nippon Kaisui, NSP), reflecting the firm's horizontal segmentation approach.

Products and services

• Pressure Flotation Treatment System (加圧浮上処理装置) A wastewater treatment system that injects pressurized water containing ultra-fine bubbles to adsorb and float pollutants for efficient purification. Achieves approximately 90% suspended solids removal and 99% oil removal, scales from a few tons/day to thousands of tons/day, and is also applicable to radioactive material removal. Sold to industrial and government clients.
• Neutralization Treatment System (中和処理装置) Treatment system that neutralizes wastewater with skewed pH (e.g., pH 2-5 or 10-12) while simultaneously removing pollutants in reaction tanks to produce dischargeable neutral water. Used for heavy metal treatment and industrial wastewater with extreme pH deviations.
• Automatic Dissolution System (自動溶解装置) Device that automatically dissolves and doses appropriate amounts of coagulants that aggregate pollutants in wastewater, integrating coagulant solution preparation and dosing into a single automated process to save labor, time, and reduce chemical waste.
• Sludge Dewatering Equipment (汚泥脱水設備) Equipment that reduces sludge moisture content from approximately 95% to 70-80% via dewatering processes, with automated flocculation, dewatering, and internal machine cleaning. Includes multi-disc and screw press type dewatering machines.
• Membrane Treatment Equipment (膜処理設備) Purification system using microporous membranes that separates only water molecules by applying pressure above osmotic pressure. Requires only a few maintenance sessions per year, eliminates the need to lift membranes for cleaning, and produces reusable water free of suspended solids and E. coli with a compact footprint.
• Biological Treatment - Activated Sludge Process (生物処理) Wastewater treatment system using microorganisms (bacteria, protozoa, metazoa) for natural purification. Includes aeration tanks with PCS static mixing diffusers for high-efficiency aeration and sedimentation tanks for separating activated sludge from purified water. Used for fishery, livestock, and agricultural processing drainage.
• Subcritical Water Treatment System (亜臨界水処理装置) Circular system that converts industrial waste into reusable materials (liquid fertilizer, compost, coal substitute fuel, snow-melting agent) using high-temperature, high-pressure steam. Processes mixed organic/inorganic waste and medical infectious waste without dioxin emissions; requires only two operators including a boiler technician.
• Radioactive Contamination Countermeasure Technology (放射能汚染対策技術) Decontamination technology applying wastewater treatment methods to radioactive contamination: pressurized water washing, flotation purification, and dehydration volume reduction. Covers removal of radioactive cesium from contaminated soil and sludge, and tritium removal from tritium-containing water. The integrated SLIX system offers multi-pattern decontamination (basic pollution purification, multi-stage coagulation reaction, subcritical water composite) for varied contamination sources.
• Environmental Restoration - River and Lake Purification (環境の修復) Natural purification-based restoration of urban rivers and lakes suffering from eutrophication. Includes turbidity reduction, algae control through nitrogen balancing, and sediment treatment using portable dewatering machines.
• CNT Ultrasound Dispersion Device (CNT超音波分散装置) Device that uses ultrasonic waves to disperse carbon nanotubes (CNT) and graphene, generating cavitation effects for stable emulsion formation and efficient multi-phase liquid mixing. Used for heat-generating materials, adsorbents, and electronic components.
• Deodorizing Equipment (脱臭装置)
